To all whom it may concern:

, Be it known that l, CHARLES FRAN-ors JENKINS, a citizen of the UnitedStates, residing at Washington, in the District of (lolumbia, have invented certain new and useful Improvements in Bottlelosing -llevices, of which the i'ollowingg,` is a specification, reference being had. therein -to the accomln making complete paper bottles, it is common to 4form tubes off any desired uni form crosssection, cut them into bottle lengths and insert closures or tops and bottoms. and, for many purposes, the most desirable closure is a disk of thin stock but to form a seat for such aclosure usually involves eX- pense which it isralways desirable tov avoid and which 'is in some cases prohibitory and, further, many 'expedients are unsatisfactory on other grounds. f

The principal `object of this invention is to avoid these dilliculties. y

The dcsiredend attained by providing` tubular rings too large to be inserted in the bottles and reducing their diameters by bending their walls sharply inward at vari ous points to form'hollow ribs and "then inserting themin the bottles to ser-ve as stops or should ers .for simple disk closures. Prac tically, the rings are formed without ex* pense, by adding cutters tothe devices which` divide the bottle tubes into -bottle lengths, and are antoniat-ically inserted by devices, herein shown, which are usually attached to the machine which automatically forms and No time is lost there synchronously with the insertion of a disk in another bottle, and the ribs being formed by the ring inserting. devices during' their inserting;` movement. It may also be observed that the ribs so formed desirably increase the width of the disk supporting` shoulder, and also serve in some cases for hinging and securing the closures.v

In the accompanying drawings, Figure l is an elevation partly in axial section of a portion of a machine embodying` my devices. Fig. 2 is a plan view of the lower portion oli the mechanism seen in Fig'. 1.,- Fig. is a section on the line 3-3, Fig. l. Figa-4l is a plan View 4of a certain ring in initial form.

In these drawings, represents a trame supporting1 a vertically movable annular die B which normally held in its highest position by springs C and limited in downward movement by shoulders D on the frame. t slightly more than a bottles height below the'plaue of the lower tace ot' the die is a support llfor bottles F. The inner walls oi' the die are outwardly inclined below so that as it descends upon an alunno' bottle,y

r'resting upon the support, the Iopen end ot' the bottle will be adjusted .to exact position y and form, whenthe die reachesthe shoulders D. Above theincliued portion of the walls,*the die is provided with inwardly gn^.ojectin, upwardly tapering lugs G shown as threev in number andeqnidistaut. The ring H to be inserted, shown in primariT form in Finne, ,u'iay be ofsubstantially they .diameter ot the/interior ot the upper part of the die. `and when 'fort-ed down through the same, by suitabledeVIces. it will assumo the torni shown in Fig: V5. the lugs otl the die pressinzov its wall inward to form ribsl Il while the intermediate portions are drawn Inward, which tends to lessen 'the' diameter. lf the parts be properly proportioued the ring will now enter and fit the interior of the bottle. The rings H are. forced through the die by a reciprocating plunger consisting of a body .portion l around the lower portion of which are arranged sections J at. a short distance from each other 'so that they can pass between the lugs of the die, these sections formingl a sortof sleeve about the body of the plunger and between shoulders K, K. Each sectionis normally held away from the inclosed portion of' the plunger body by one or more springs L, and the outward movement of all the sections is'limited by one or more rings M lying in au annular groove or grooves NA in the exterior ofthe sleeve as a whole.. The lower end o the sleeve is preferably tapered `and -just above this tapered portion the sleeve is of suchl diameteras to fit the ring in its primary condition. Above the place of such ring` the sleeve has an annular shoulder of a width slightly less than the thickness of the ring` H. The arrangement is such that the plun-lV ger, die, and bottle are in alinementNvith the plunger, when raised, more than a rings.

width above the die. A ring H being placed in position over the die and adjusted, usually by automatic devices not shown, the descending plunger enters the ring` and its shoulder engaging the upper edge of the' and as the ring leaves the lugs it passes into the bottle, Where it is left byv the retreating plunger. Certain machines insert the disk closure l before the insertion of the ring as just described, while others insert it afterward, and obviously the last inserting plunger may have such stroke as to leave the ring and disk in either the upper or lower end of the bottle, as may be desired. The dis tance of the bottle below theraised die is small and practically no 'special devices are ordinarily required for strippingthe bottle from the plunger, and hence in this instance none are. shown. Y

lVhat I claim is:

1. The combination with an annular die provided with rounded internal projections at intervals, of a co-acting reciprocating plunger having lateral recesses for said projections and a shoulder to engage a suitable ring and force it through the die; whereby said projections bend the ring into said recesses and thus provide it in turn with internal projections.

2. The combination Awith an annular die provided at intervals with internal projec tions tapered toward the entrance face of the die, of a radially compressible co-acting reciprocating plunger having longitudinal external channels in registry with said projections and further having a shoulder adapted to engage the edge of a suitable ring, as the plunger advances toward the die, and force it through he latter; whereby the ring'is passed into said. channels by said projection, and thereby decreased in diameter.

'3. The combination with a bottle support, of an annular die and a coacting recipron Aeating plunger all alininfr; said plunger being adapted for radial compression` and having a shoulder to engage one edge of a ring to be inserted in a bottle and further having at intervals external longitudinal channels, and said die having at corresponding intervals internal lugs tapered toward its entrance face. ,i

4. The combination with a'bottle support, of an annular spring supported forming die,

at intervals, mounted at slightly more than ,toward the support, means for limiting the movement of the die, and a co-acting reciprocating radially com ressible jjilunger provided with external ongit-udinal channels registering with said lugs and with a shoul der adapted to engage the edge of a suitable ring and force it through the die inlo a bottle resting on said sup iort.
